new partition is read only why?????

Asked by yairsuari

i had an unused sction in my hard drive. i created a new partition on it, formated it (ext 3) mounted it (to /doc)
but now i can only write to it as su (even if i did su 755 on the device and the mount point)
any ideas??
some outputs:
fdisk -l
Disk /dev/sda: 26.8 GB, 26843545600 bytes
255 heads, 63 sectors/track, 3263 cylinders

fdisk -l is showing that sda3 is formatted a FAT32 (vfat). I suggest using GParted to reformat the partition so that it is ext3, then you should have no problems. You can change your fstab to be vfat and then set the appropriate mount options on it, but ext3 is much easier to deal with since it has the type of permissions associated with it that linux likes.
GParted is on the LiveCD, but can be installed to your regular system by running
sudo apt-get install gparted
It can be accessed from System->Administration->Partition Editor

 the fstab options users,noauto,rw will allow you to read and write to the partition
